18z 3km NAM model
Simulated Radar Forecast valid 7 PM Thursday to 1 AM Saturday — This model does show a few showers in far northern Minnesota Thursday night through Friday evening, but I don’t think this will be a real big deal, and these showers should stay north of the Twin Ports.

12z European Computer Model ECMWF 9-5-2018
Long range computer models remain consistent in showing an upper level ridge expanding for the middle to end of next week with a period of above normal temperatures looking quite likely for the upper Midwest. Note: As we move into mid September, our average highs in the Northland are mainly in the mid to upper 60s, average lows mainly in the 40s. Per model data we could be looking at daytime highs from 75 to 85 degrees, overnight lows around 60 degrees for the mid to end of next week (September 12-16)
Weather Synopsis
Dew points have crashed today! 24-hours ago we had dew points in the mid 60s to low 70s around the Northland, fast forward to 24-hours later and dew points this afternoon are only in the mid 30s to mid 40s, a sure sign of fall!
Some high level clouds have been streaming SW-NE through eastern Minnesota and northwest Wisconsin today, mainly sunny skies for northern Minnesota. Highs today were in the mid 60s to around 70 degrees which is close to average for early September.
We’re settling into a rather typical pattern for early September where will have cool nights followed by mild afternoons, this should help kick start the fall foliage in coming days/weeks.
High pressure will be over the upper Midwest through Thursday night giving us clear to partly cloudy skies. Lows tonight will range from the mid 30s to low 50s (warmest temps close to Lake Superior) Highs Thursday look similar to Wednesday’s highs with readings in the mid 60s to around 70 degrees.
A cold front approaches from the north on Friday, there could be a few showers tied to this front that would affect far northern portions of Minnesota on Friday, but overall it still looks mainly dry in most of the Nortlhland Thursday, Friday and Saturday.
Highs Friday and Saturday are forecast to range from the mid 60s to mid 70s with easterly breezes expected near Lake Superior both days.
